Tawaf begins at the corner of the Black Stone (marked by a green line/light) and consists of seven circuits anticlockwise, with the Kaaba on your left. Ritual purity (wudu) is required.
Men are recommended to uncover the right shoulder (idtiba‘) and to walk briskly in the first three circuits (raml) where possible. Between the Yemeni Corner and the Black Stone it is common to say: “Rabbana atina fid-dunya hasanah …”. Otherwise, remembrance of Allah and personal supplications in any language are possible.
